For example, the smart glass adjusts the sunlight or the headlamp light of the opposite vehicle, which is an obstacle to driving when driving a vehicle by changing the light transmittance by adjusting the applied voltage.

Therefore, the smart glass requires a power supply to change the light transmittance according to the external environment, and for this, a wireless method is applied as a smart glass power transmission system for a vehicle. The reason for this is that the door glass is configured to only move up/down through the cable linkage connected to the motor driven by the external power supply.

For example, the smart glass wireless power transmission system embeds a power receiving module and a power transmitting module inside the door, and power supplying power to the smart glass and the transmitting coil (primary coil) of the power transmitting module where power is supplied from a battery. Ground induction and magnetic resonance between the receiving coils (secondary coils) of the receiving module are used.

For example, the holder bracket 7 is connected to the door carrier panel 5 and the smart glass 9, and in particular, the power connector 21 of the connector module 20 constituting the smart glass wired power transmission system 10 is It functions as a connecting part.

For example, the smart glass 9 functions as a window of the door 3, rises/falls by driving the door regulator member 6, and is attached to a smart film to control the applied voltage. 2), the power or voltage is changed.

From this, the smart glasses 9 display various smart images while controlling the light of the sunlight/vehicle headlamp by changing the light transmittance by changing the power or voltage.

To this end, the smart glass 9 is a single layer film made of any one of a Suspended Particle Device (SPD) film, a Polyvinyl Butyral (PVB) film, and an Ethylene Vinyl Acetate (EVA) film, or a multilayer (film) formed by overlapping them. Multi Layer Film) is placed between the glasses.

In particular, the cable module 30 maintains an electrical connection state between the connector module 20 and the inverter 70 in the rising/lowering movement of the smart glass 9 according to the driving of the door regulator member 6 .

For example, the inverter 70 provides power, is mounted on the dry side side, and is connected to a vehicle power source or connected to a battery to supply power. In this case, the dry side is an interior side, and is defined as a direction toward the interior of the vehicle when the door 3 is mounted on the vehicle 1 .

In particular, the inverter 70 varies the applied voltage and is electrically connected to the connector module 20 via the cable module 30 to apply it to the power transmitter 25 (see FIG. 2 ) of the connector module 20 . change the power

For example, the grommet 80 (see FIG. 8 ) is a cable passing from the dry side to the wet side of the door carrier panel 5 so as to be connected from the connector module 20 to the inverter 70 . The power cable 50 (see FIG. 8 ) of the module 30 is wrapped around the cable hole 5a formed in the door carrier panel 5 . In this case, the grommet 80 is made of rubber.

Furthermore, the smart glass wired power transmission system 10 may include an inverter controller 90 and an operation button 100 .

For example, the inverter controller 90 recognizes the operation of the operation button 100 and outputs an inverter control signal A to control the power of the inverter 70 by controlling the power transmission unit 25 of the connector module 20 ( 2) controls the degree of variability with respect to the power applied to it. In this case, the inverter controller 90 may be integrated with the inverter 70,

To this end, the holder bracket 7 is divided into a glass holder 7a, a connector holder 7b and a hook 7c. In this case, the glass holder 7a fixes the lower end of the smart glass 9 inserted in the shape of a “U” cross-section with a screw or the like, and the connector holder 7b is a glass holder ( 7a) has a structure integrated with the power connector 21 and has an internal space so that the power connector 21 is inserted, and the hook 7c has a structure integrated with the connector holder 7b on one side of the rectangular body. It is coupled with the release lever 23 of the connector 21 .

Therefore, the power connector 21 and the holder bracket 7 are attached/removed with an elastic leg locking structure (refer to section A-A).

For example, the elastic leg locking structure has a leg shape cut to have elastic force on each of the release lever 23 and the hook 7c. From this, the leg elastic force of the hook 7c spreads while the power connector 21 is inserted into the connector holder 7b, then returns to the fitted state to form a fixing force, and the leg elastic force of the release lever 23 is It is elastically deformed by a pressing operation that applies a certain force to the release lever 23 (or the hook 7c) with the tool 200 (refer to FIG. 6 ) to release the fixing force, and then return to the uncoupled state. In this case, of course, the inter-leg locking structure having elastic force is a typical structure.

For example, the power transmitter 25 is connected to the electric wire 27, is attached to the surface of the smart glass 9, so that the light transmittance for the smart glass 9 is changed by the application of power supplied through the electric wire 27 do. In this case, the power transmitter 25 is provided on a part of the smart film so as to be electrically connected to the smart film embedded in the smart glass 9 .

For example, the electric wire 27 is a power line made of copper or an equivalent material, and is connected to the power transmitter 25 while being inserted into the wire terminal 22 of the power connector 21 to transmit the power of the inverter 70 to power. It is transmitted to the transmitter 25 .

Referring to FIG. 3 , the connector module 20 is detachably coupled to each other by applying a connector assembly structure using the release lever 23 of the power connector 21 and the hook 7c of the holder bracket 7 .

For example, in the release lever 23 of the power connector 21, the coupling of the hook 7c of the holder bracket 7 is a locking structure between the legs of the hook 7c and the legs of the release lever 23 (see section A-A) ), and the leg has an elastic force so that it can be elastically deformed against an external force.

And the wire terminal 22 has a structure for biting and fixing the strand of the inserted electric wire 27, and the terminal 47 of the holder mounting bracket 40 constituting the cable module 30 inserted into the inner space of the rectangular connector body. ) (refer to FIG. 5) and the electric wire 27 are electrically connected.

In addition. 4 to 6 illustrate that the holder mounting bracket 40 is composed of a cursor 41 , a lead frame 45 , a screw 48 and a protective cap 49 .

Referring to FIG. 4 , the cursor 41 is made of a plate body having a plurality of ribs having rigidity formed therein, and the lead frame 45 is formed in an “H” shape and the cursor 41 is formed through a screw 48 as a medium. is fixed to the plate body of

For example, the cursor 41 forms a holder grip 41a, a frame channel 41b, a connector groove 41c, and a cable connection part 41d on the plate body. In this case, the holder grip 41a forms the upper part of the plate body and is attached to the connector holder 7b of the holder bracket 7 . The frame channel 41b is formed as an “H”-shaped groove on one side of the plate body to seat the lead frame 45. The connector groove 41c is the connector module 20 of the frame channel 41b. The power connector 21 is drilled through one side of the plate body so that it is inserted and protruded.

It is combined with the bracket (7). Also, the frame channel 41b is formed as an “H”-shaped groove in the same manner as the lead frame 45 .

For example, the lead frame 45 includes a frame body 46 and a terminal 47 . In this case, the frame body 46 forms a first terminal connector 46a (eg, a left part) and a second terminal connector 46b (eg, a right part) that are vertical to both left and right sides of the horizontal connection section. to form an “H” shape, and the terminals 47 are arranged along the first terminal connector 46a, the frame body 46, and the second terminal connector 46b, It consists of 1 and 2 terminals 47a and 47b.

In particular, a screw holder 46c is formed on each of the first and second terminal connectors 46a and 46b, and the first terminal connector 46a forms a screw holder 46c downward while the second terminal connector 46b forms the screw holder 46c upwards.

For example, the screw 48 fixes the lead frame 45 to the cursor 41 . To this end, the screw 48 is composed of two, one passes through the screw drilled in the first terminal connector 46a and is fastened to the cursor 41 while the other penetrates the screw drilled in the second terminal connector 46b. It is engaged with the cursor 41 . Therefore, one of the screws 48 is located below the lead frame 45 from the side of the first terminal connector 46a while the other is located above the lead frame 45 from the side of the first terminal connector 46a.

Referring to FIG. 5 , the protective cap 49 is coupled to the cable connection part 41d of the cursor 41 to surround the second terminal connector 46b of the lead frame 45, and the second terminal connector 46b and It blocks the penetration of foreign substances into the connection part of the power cable 50 .

In particular, referring to section B-B of FIG. 5 , one side of the first and second terminals 47a and 47b is connected to the power connector 21 of the connector module 20 from the first terminal connector 46a side. On the other hand, referring to section C-C of FIG. 5 , opposite sides of the first and second terminals 47a and 47b are connected to the power cable 50 from the second terminal connector 46b side.

It exemplifies that the lever 23 can be separated simply by lowering the cursor 41 in the elastically deformed state.

7 and 8 show the connection state of the power cable 50 and the lead frame 45 using the same, the tensioner 60 and the inverter 70 .

Referring to FIG. 7 , the power cable 50 connects the separation distance formed by the connector module 20 and the inverter 70 with a flexible wire length, and the connector module 20 for the fixed inverter 70 . It absorbs the separation distance changed by the up/down movement of the flexible wire by changing the length of the flexible wire.

To this end, the power cable 50 is made of a flexible wire 51 of a predetermined length having a flexible wire length, and a first cable connector 51a is provided at the right cable end of the flexible wire 51. A second cable connector 51b is provided as the left cable end. In this case, the predetermined length is a distance formed by the lead frame 45 at the maximum rising position of the inverter 70 and the smart glass 9 in a state where a partial length is wound around the tensioner 60 . Therefore, the predetermined length is the length of the flexible wire and is equal to the separation distance formed by the connector module 20 and the inverter 70 .

For example, the flexible wire 51 includes a +/_ wire and a GND wire. The first cable connector 51a among the first and second cable connectors 51a and 51b is provided on one side of the flexible wire 51 , and the second cable connector 51b is on one side of the flexible wire 51 . provided

In the longitudinal direction of the winding shaft 61a so that the connecting shaft 61b extending from the It consists of a cable slit 61c having a gap structure. In this case, the connecting shaft 61b has a smaller diameter than the winding shaft 61a to form a concentric circle with the winding shaft 61a.

For example, the fixed body 63 is a spring housing that forms a concentric circle with the connection shaft section of the central shaft 63a so that the central shaft 63a coupling the rotating body 61 and the cover 65 and the spring 67 are accommodated. (63b), a screw hole is drilled and consists of a fixing flange (63c) protruding from both left and right sides of the spring housing (63b). In this case, the central shaft 63a forms a concentric circle with a difference in diameter between the connection shaft section to which the connection shaft 61b of the rotating body 61 is coupled and the cover shaft section to which the cover 65 is fitted and coupled, and the spring housing 63b ) form a concentric circle with a difference in diameter so that a spring space is formed between the central axis 63a.

For example, the cover 65 is fixed to the central axis 63a of the fixed body 63 to block the separation of the rotating body 61 . To this end, the cover 65 has a “U” cross-sectional structure in which a shaft hole to be fitted into the central shaft 63a of the fixed body 63 is drilled in the center, and a gap structure interposed at an angle with respect to the central shaft hole. By forming the cable slit 65c of

For example, the return spring 67 is made of a coil spring having bent spring ends at both ends, and the central axis 63a of the fixed body 63 is wrapped around the connection shaft 61b of the rotating body 61 . ) and the spring housing (63b) is built into the spring space.

Referring to FIG. 10 , the rotating body 61 is assembled with the fixed body 63 in a state in which the flexible wire 51 of the power cable 50 is partially wound. Therefore, the winding shaft 61a winds the flexible wire 51 of the power cable 50 so that when the door regulator member 6 is driven, the power cable 50 is wound by the up/down movement of the smart glass 9. The rotating body 61 is rotated through the movement to be lost or released.
